.net 拉力休息API坏了吗？

我有一个代码片段，它一直在工作，直到上周末的某个时候。 这很简单，对于给定的项目名称，请给我与之关联的团队成员。 查询本身可以工作，并给我一个结果集，但是当我尝试迭代任何字典时，我会得到一个异常

下面是片段

            try
            {
                Request projectRequest = new Request("project");
                projectRequest.Fetch = new List<string>()
                                            {
                                                "Name",
                                                "Owner",
                                                "State",
                                                "Description",
                                                "Workspace",
                                                "TeamMembers",
                                                "Releases"};
                String projectName = rallyProject.Text;
                // get me results for the given project
                projectRequest.Query = new Query("Name", Query.Operator.Equals, projectName);
                QueryResult queryProjectResults = restApi.Query(projectRequest);
                DynamicJsonObject myProject = queryProjectResults.Results.First();

                myProjectReference = myProject["_ref"];

                var projectState = myProject["State"];
                var workspace = myProject["Workspace"];
                myWorkspaceRef = workspace["_ref"];
                string currentUser = userComboBox.Text;

                userComboBox.DataSource = null;
                userComboBox.Items.Clear();
                userComboBox.Sorted = false;

                // iterationComboBox.Items.Add("Unscheduled");
                userMap.Clear();
                List<string> userList = new List<string>();
                userList.Add("");

引发的异常是 无法将类型“Rally.RestApi.DynamicJsonObject”隐式转换为“System.Collections.IEnumerable”。存在显式转换。是否缺少强制转换

如前所述，这已经运行了几个月，直到上周左右。机器上唯一改变的是正常的windows更新

任何建议都是非常受欢迎的， 提前谢谢

我可以在使用最新的dll和WS-API v2.0时复制相同的错误，我们鼓励用户这样做，因为在今年6月之后将不支持WS-API的1.43

为了使您的代码能够使用WS-API的v2.0，我稍微修改了您的代码，以单独调用来获取TeamMembers集合的对象：

Request teamRequest = new Request(myProject["TeamMembers"]);
                QueryResult teamResult = restApi.Query(teamRequest);
                foreach (var teammate in teamResult.Results)
                {
                    userMap.Add(teammate["_refObjectName"], teammate["_ref"]);
                    userList.Add(teammate["_refObjectName"]);
                }

在Rally Web Services API的v2.0中，出于性能原因，我们取消了在同一响应中返回子集合的功能。在v2.0中，获取集合将返回一个对象，该对象包含计数和从中获取集合的url。在旧版本的WS-API中，某些fetch列表会创建大量递归调用，并且fetch中包含的所有集合都会使调用非常昂贵。在WSAPIv2.0中，这不会发生，因为必须进行单独的调用才能获取集合的对象

如果您在针对WS-API 1.43或更早版本运行代码时遇到此问题，请重试，因为昨天我们遇到了一个临时问题，在获取包含的版本时影响了1.43。这一问题在同一天得到解决

以下是适用于WS-API v2.0的完整代码：

static void Main(string[] args)
            {

                    Request projectRequest = new Request("project");
                    projectRequest.Fetch = new List<string>()
                                                {
